Quinck's Tube Method

This apparatus is used to determine Susceptibility of paramagnetic sample by using quinck's tube method.

Salient features:Compact electromagnetGauss meter

Principle and Working:Quincke's method is based on the force experienced by a magnetised material in a non-uniform magnetic field and is a version of Gouy's method, which is specially adapted for liquids. On the basis of Susceptibility, a substance can be classified as diamagnetic, paramagnetic and ferromagnetic substance, which is an important observation in material science. In the present setup, the liquid moves under the action of the total force F until it is balanced by the pressure exerted over the area A due to a height difference 2h between the liquid surfaces in the two arms of the U-tube. Allowing for the susceptibility ÷ and density ñ of a a the air which the liquid displaces, it follows that,

A (X-Xa ).(B2-Bo2)/2 μ =2Ah (ρ -ρa)g

where g is the acceleration due to gravity,ρ density of liquid, so that

Once you submit a review to us, it is read only. We do not modify submitted review content under any circumstance, at any time during our professional moderation. The intention of reviews, is to guide customers into quality purchase decisions based on unbiased relevant feedback

Mention of Price: Do not share a definitive price of the reviewed product.

Promotional Content / Links / Cross-promotion Rules: Review content is only useful to users who don't have to sift through cross promotional clutter or links inside. Adding reference links to products and relevant places is encouraged

Privacy: Do not publicize private information of individuals and/or their business interests, people’s full names, email address, URL's, street addresses, other customers names and / or suppliers without written permission, unless they refer to service providers who are commonly identified by or commonly share their own full names.

Conflicts of Interest: User contributions should be unbiased and objective. For example, we will decline reviews made by the owners of their own product supplier, friends’ or relatives’ business, peers or competitors in the same industry.

Contradiction / Error: Star rating does not correspond with the written review and is obviously a user error.

Relevance: Review is written for a different product than listed; reviewer states that they received a different product than ordered; review is 100% a review of the service or shipping, and makes NO mentions or is irrelevant of the product itself. Review solely contains random characters or meaningless word strings, or is otherwise irrelevant to the product, or so poorly written as to be unintelligible.

Validation / Guess: Reviewer has yet to make a purchase or the reviewer has no experience with the specific product or retailer, or is submitting their review prior to receiving the product.
